I'm preparing a new experiment video called Redirecting Grid. It's a follow up of my previous experiments using polarization twister. They all show that microwave coming out of the aperture don't have the same angle as the incoming wave.
In polarization twister, the orientation of the receiver is perpendicular to that of the transmitter. But in the new experiment, they will have the same orientation. For convenience, I only take vertical polarization, although the horizontal can also be done in principle.
The grid works based on aliasing effect. The conductors in the grid are made more sparse than half of the wavelength.

The results of my experiments using microwave have convinced me that matters react with electromagnetic wave by creating reactive waves.  They interfere with original wave to give final result which can be measured. I think this model can explain many phenomena in optics and electromagnetism.

"Normal" optical media are merely materials with specific structural properties, such as 3d symmetry. Birefringence is caused by linear asymmetries. Chirality is caused by rotational  asymmetry.

I've uploaded a new video investigating further into the behavior of microwave when interacting with a redirecting grid. Additional conductors to the grid change the behavior depending on their positions on the grid.

I'm glad to help. If you have interesting ideas, or curious about some aspects of the experiments, but have no access to necessary resources to make them happen, please let me know. Maybe there's something I can do to help.

Someone may point out that the redirecting grid is demonstrating phenomenon of diffraction, because it produces similar effect to an optical equipment called diffraction grating. But as I mentioned in other threads, the change in direction of microwave propagation is the result of interference from several waves reflected by each conductors.

Here is another video about redirecting grid. This time the slots in the corrugated board are mostly filled with conductors.

The results so far support the idea that observed intensity is the result of superposition among individual reactive wave produced by each conductor which acts like an antenna. In this case, their shapes are thin cylinders.

My next video using microwave transceiver is about interferometer. I hope to get a better understanding on the behavior of beam splitter. Perhaps it can help demystifying many experimental results involving its usage which many people said to be weird or even mind blowing.

I'd like to keep my videos short to reduce the computational resources in editing them. So I'll split the experimental series into several videos covering each very specific topics.

I've done recording the experiment of standard interferometer using microwave transmitter and receiver, a beam splitter, and two flat reflectors. I should have done this earlier since the equipments required to do the experiment have already been available. When I bought the transceiver, the half mirror was included in the package.

The next experiment I'm already planning is about polarizing interferometer. It has the same setup as standard interferometer, but the half mirror beam splitter is replaced by a polarizer. It looks like we'll get interesting results.

In quantum mechanics, the quantum eraser experiment is an interferometer experiment that demonstrates several fundamental aspects of quantum mechanics, including quantum entanglement and complementarity.[1][2][3] The quantum eraser experiment is a variation of Thomas Young's classic double-slit experiment. It establishes that when action is taken to determine which of 2 slits a photon has passed through, the photon cannot interfere with itself. When a stream of photons is marked in this way, then the interference fringes characteristic of the Young experiment will not be seen. The experiment also creates situations in which a photon that has been "marked" to reveal through which slit it has passed can later be "unmarked." A photon that has been "marked" cannot interfere with itself and will not produce fringe patterns, but a photon that has been "marked" and then "unmarked" will interfere with itself and produce the fringes characteristic of Young's experiment.[1]

A very common misunderstanding about this experiment is that it may be used to instantaneously communicate information between two detectors. It is important to understand the role of the coincidence detector in this experimental setup. The linear polarizer in the top path is effectively filtering out half the entangled photons, and via the coincidence detector, is filtering out the corresponding photons in the bottom path. The coincidence detector can only function by comparing data from both sensors, making it impossible to use this setup for instant communication.

In Brief

The Facts:
At the quantum scale, what we do in the present can impact what happens in the past. This is shown through what's known as the quantum delayed choice choice, or quantum eraser experiment.

Reflect On:
Why are factors associated with consciousness directly intertwined with physical material matter at the quantum scale? What does this mean when it comes to our physical material world in relation to our thoughts, perceptions, feelings and emotions?

One of the founding fathers of quantum theory, Max Planck, who is often credited with originating quantum theory – a feat that won him the Physics Nobel Prize in 1918 – once stated: “I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as exiting, postulates consciousness.”

Here's another one
https://en.wikipedia.org/wiki/Wheeler%27s_delayed-choice_experiment#Experimental_details
Quote
John Wheeler's original discussion of the possibility of a delayed choice quantum appeared in an essay entitled "Law Without Law," which was published in a book he and Wojciech Hubert Zurek edited called Quantum Theory and Measurement, pp 182–213. He introduced his remarks by reprising the argument between Albert Einstein, who wanted a comprehensible reality, and Niels Bohr, who thought that Einstein's concept of reality was too restricted. Wheeler indicates that Einstein and Bohr explored the consequences of the laboratory experiment that will be discussed below, one in which light can find its way from one corner of a rectangular array of semi-silvered and fully silvered mirrors to the other corner, and then can be made to reveal itself not only as having gone halfway around the perimeter by a single path and then exited, but also as having gone both ways around the perimeter and then to have "made a choice" as to whether to exit by one port or the other. Not only does this result hold for beams of light, but also for single photons of light. Wheeler remarked:

The experiment in the form an interferometer, discussed by Einstein and Bohr, could theoretically be used to investigate whether a photon sometimes sets off along a single path, always follows two paths but sometimes only makes use of one, or whether something else would turn up. However, it was easier to say, "We will, during random runs of the experiment, insert the second half-silvered mirror just before the photon is timed to get there," than it was to figure out a way to make such a rapid substitution. The speed of light is just too fast to permit a mechanical device to do this job, at least within the confines of a laboratory. Much ingenuity was needed to get around this problem.

After several supporting experiments were published, Jacques et al. claimed that an experiment of theirs follows fully the original scheme proposed by Wheeler.[14][15] Their complicated experiment is based on the Mach–Zehnder interferometer, involving a triggered diamond N–V colour centre photon generator, polarization, and an electro-optical modulator acting as a switchable beam splitter. Measuring in a closed configuration showed interference, while measuring in an open configuration allowed the path of the particle to be determined, which made interference impossible.

In such experiments, Einstein originally argued, it is unreasonable for a single photon to travel simultaneously two routes. Remove the half-silvered mirror at the [upper right], and one will find that the one counter goes off, or the other. Thus the photon has traveled only one route. It travels only one route. but it travels both routes: it travels both routes, but it travels only one route. What nonsense! How obvious it is that quantum theory is inconsistent!

Especially, this DIY experiment is the main reason I planned to investigate further using microwave.

You can see its front picture. It uses a device to split a light beam into 2 different directions. Hence a beam splitter.

That's a light source, a laser, not a beam splitter.

The talk does mention beam splitters later, but they are on the other side of the frame and labelled as half silvered mirrors.

Since there is no beam splitter in that experiment, no experiments you do to clarify your personal understanding of the splitter will help explain the weird effects.

In that experiment, the beam splitter is the double slit and splitting crystal.  An ordinary glass prism can also be used as a beam splitter. With certain incoming angle, some of the light will be reflected while the other will be refracted.

Since the video is not the only source mentioning the weird effects in interferometer, proper understanding on how each of its components work is essential to find out the explanation, instead of just shrug and simply accept that the universe is weird.
